Influence of sugar label formats on consumer understanding and amount of sugar in food choices: a systematic review and meta-analyses

Abstract: Context Reducing population intakes of sugar has become a focus of many national and international public health policies. Packaged foods and beverages are key contributors to sugar intakes, and food labels can be an effective tool to reduce sugar consumption. Objective The aim of this systematic review was to examine the influence of sugar label formats on 2 outcomes: consumers’ understanding of sugar information, and the am… Show more

“…Many studies have tested the influence of different label formats on consumers' food choices or purchases, and mixed results have been found according to the types of label and food category tested, the methodology used, and participants' nationality ( 37 , 39 , 44 50 ). A systematic review investigating sugar label formats and their influence on consumers' food choice has demonstrated that interpretive information (e.g., colours, “high in sugar” text, warnings, or health messages) is more effective than the standard NIP in encouraging consumers to choose foods with less sugar ( 31 ). The results of the present study showed that the sugar label formats tested did not significantly decrease consumers' choices for products high in sugar.…”

“…The first author moderated all focus groups with the support of two observers who took notes. A semi-structured interview guide was developed based on the literature, including our previous systematic review investigating sugar labelling formats and consumers' understanding ( 31 ). The interview guide included open-ended questions that covered participants' perception of sugar (e.g., What do you understand by sugars?…”

“…Warning labels perhaps have the strongest evidence with regard to discouraging purchases of foods high in nutrients of concern, with recent systematic reviews of experimental and quasi-experimental data showing that warnings reduce the selection of unhealthy products by 26% to 36% [ 35 , 36 ]. Another recent review, which was focused on sugar, found that warnings were the most effective at increasing consumers’ understanding of the high nutrient content in foods [ 37 ]. Real-world evidence from Chile, the first country to implement mandatory front-of-pack warnings, found that warning labels were linked to a 24% decrease in purchases of unhealthy foods [ 38 ] and helped both parents and children identify unhealthy food and drinks and discourage their consumption [ 39 ].…”

“…To our knowledge, there is no evidence from experimental studies or real-world evaluation studies that HSR leads to healthier food purchases [ 46 , 47 , 48 ]. Evidence in favor of the industry-promoted Guideline Daily Amount (GDA) system is the weakest of all, with an array of both experimental and real-world evaluation studies from across the globe finding that, relative to almost all other FOPL types, the GDAs are poorly understood, take the most time to evaluate, and are the least effective at influencing purchases [ 37 , 47 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ].…”

“…Moreover, a previous study [ 37 ] showed that the sugar content of a product is a key component in food choices. Finally, sugar labels have been shown to be quite effective in guiding consumers to products with lower sugar contents [ 38 ].…”
